[0002] In the electric scooter industry, the front fork is a crucial component, as its performance and ease of installation directly affect the overall quality and user experience. Traditional electric scooter front forks present numerous inconveniences and drawbacks during installation.
[0003] The installation of the thru-axle in traditional electric scooter models also presents a challenging problem. Traditional installation methods rely on tightening bolts to secure the thru-axle, but during this process, the thru-axle is prone to slipping in the open position. Due to the lack of reliable limiting devices, the thru-axle is difficult to maintain in the ideal installation position, and this slippage severely affects installation accuracy.
[0004] Meanwhile, in traditional fork installation, the fork shoulder and damper need to be fixed with bolts. When tightening the bolts, the top of the damper is inserted into the fork shoulder, which is a blind spot, making it difficult to align the threaded holes. This results in long installation time and low efficiency. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a modular electric scooter front fork, including a head tube 1. A fork shoulder 2 is fixedly connected to the lower surface of the head tube 1. The head tube 1 and the fork shoulder 2 are fixed by welding. A damper 3 is provided at the bottom end of the fork shoulder 2. The damper 3 is divided into an inner tube and an outer tube, which is existing technology and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case. A quick-release component is provided at the bottom end of the damper 3, which facilitates the installation and removal of the damper 3. A positioning component is provided at the top end of the damper 3, which facilitates the installation of the cylinder shaft 54.
[0031] Reference Figure 1 - Figure 3 The quick-release assembly includes a first slot 51, and a second slot 52 is fixedly connected to the lower surface of the head tube 1. The second slot 52 and the first slot 51 are identical in all other parts except for the size of their inner openings. A rubber ring 53 is fixedly connected to the inner wall of the second slot 52. A cylindrical shaft 54 is inserted into the left end of the second slot 52. A rod 55 is fixedly connected to the right surface of the cylindrical shaft 54. The diameter of the rod 55 is smaller than that of the cylindrical shaft 54. The rod 55 can pass through the second slot 52. A retaining ring 56 is fixedly connected to the left end of the outer wall of the cylindrical shaft 54. The retaining ring 56 is used to snap the cylindrical shaft 54 in place to ensure stability during installation. A mounting bolt 58 is threaded through and connected to the left surface of the cylindrical shaft 54. A washer 57 is fitted onto the outer wall of the mounting bolt 58. The washer 57 serves to prevent slippage.
[0032] Reference Figure 1 - Figure 3The positioning component includes a positioning groove 401. The inner wall of the damper 3 is elastically connected to a positioning block 42 by a compression spring 41. The positioning block 42 and the positioning groove 401 fit together. The front surface of the damper 3 is threaded through and connected to a fixing bolt 43.
[0033] Reference Figure 1 - Figure 3 The first opening 51 is fixedly connected to the lower surface of the damper 3. The first opening 51 is located to the right of the second opening 52. The insert rod 55 is inserted into the inner wall of the first opening 51. The cylinder shaft 54 cannot pass through the first opening 51 and will be blocked. The rubber ring 53 is snapped into the left side of the fixing ring 56 to position the cylinder shaft 54. The inner diameter of the first opening 51 is smaller than the inner diameter of the second opening 52. Two sets of gaskets 58 and mounting bolts 57 are provided. The two sets of gaskets 58 and mounting bolts 57 are arranged symmetrically in the transverse direction to fix the cylinder shaft 54 and the insert rod 55. The mounting bolt 57 on the right side passes through and is threadedly connected to the right surface of the insert rod 55.
[0034] Reference Figure 1 - Figure 3 The top of the damper 3 is inserted into the lower surface of the fork shoulder 2. When inserted, the positioning block 42 is squeezed by the fork shoulder 2. The positioning block 42 is inserted into the inner wall of the positioning groove 401. The right surface of the positioning block 42 is set as an arc surface. When squeezed, the positioning block 42 will move to the left and retract into the damper 3 to release the obstruction. The fixing bolt 43 passes through and is threadedly connected to the front surface of the fork shoulder 2, which can fix the fork shoulder 2 and the damper 3. The positioning block 42 passes through and is slidably connected to the right surface of the damper 3. One end of the compression spring 41 is fixedly connected to the left surface of the positioning block 42, and the other end of the compression spring 41 is fixedly connected to the inner wall on the left side of the damper 3. When the positioning block 42 moves to the left, it will squeeze the compression spring 41 to generate a reaction force.
[0035] Working principle: When using this device, first insert the damper 3 and the fork shoulder 2. During insertion, the arc surface of the positioning block 42 will be squeezed, and the positioning block 42 will retract into the damper 3 to release the obstruction. It will also squeeze the compression spring 41 to generate a reaction force. When the damper 3 and the fork shoulder 2 are inserted, rotate the damper 3. When the positioning block 42 and the positioning groove 401 are aligned, the compression spring 41 will push the positioning block 42 and the positioning groove 401 to insert and position the damper 3. Then, use the fixing bolt 43 to fix the fork shoulder 2 and the damper 3.
[0036] Then, insert the spool 54 into the second slot 52 from left to right. When the insert rod 55 is fully inserted into the first slot 51, the spool 54 will contact the first slot 51 to form a block. During this process, the retaining ring 56 will squeeze the rubber ring 53 to deform it and gradually move to the right side of the rubber ring 53. The rubber ring 53 will recover under its own elasticity and lock the retaining ring 56 to ensure the stability of the spool 54. Then, use the mounting bolts 57 and washers 58 to fix the spool 54 and the insert rod 55. Before inserting the spool 54 and the fork shoulder 2, first straighten the wheel. After installation, the wheel will be located on the outer wall of the spool 54.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
